target/arm/cpu: Ensure we can use the pmu with kvm

We first convert the pmu property from a static property to one with
its own accessors. Then we use the set accessor to check if the PMU is
supported when using KVM. Indeed a 32-bit KVM host does not support
the PMU, so this check will catch an attempt to use it at property-set
time.
